The all-important bit – selecting your hard-hat! Once checked-in, you’ll be pointed in the direction of the train station (this is a very short walk from reception), where you’ll grab a helmet and meet your tour guide.

Reimagined for 2025, you’ll experience 10 awe-inspiring slate chambers, discover old miners’ tales via incredible AV and light shows, get the chance to interact with some real artefacts and meet some historical characters.
